A)
Pumpkin is a large round fruit with a thick orange skin and large seeds. Pumpkins are 90% water but they contain potassium and vitamin A. Six of seven continents can grow pumpkins. Nowadays pumpkins have come to symbolize not only the lovely color of the autumn but the spirit of the season as well. A sizable number of movies were made with pumpkin and Halloween themes. Most memorable, perhaps, is the pumpkin carriage in Cinderella.
B)
Pumpkins are believed to have originated in North America. Native American Indians ate pumpkins centuries before the Europeans landed. Seeds from related plants have been found in Mexico dating back to 7000 to 5500 B.C. References to pumpkins date back many centuries. The word pumpkin originated from the Greek word for "large melon" which is "pepon." "Pepon" was changed by the French into "pompon." The English changed "pompon" to "Pumpion."
C)
In the United States, pumpkins go hand in hand with the autumn holidays of Thanksgiving, and, of course, Halloween. At almost every Thanksgiving table is the customary 'Pumpkin Pie'. Pumpkins are carved into decorated lanterns for Halloween. Pumpkin is one of the important symbols of the harvest festival and has been an American-favourite for over 400 years now. A lot of autumn festivals are dedicated to the pumpkin. Farmers from all over the US compete to determine who has grown the heaviest pumpkin.
D)
In the USA, pumpkin is a very popular Thanksgiving dish. It is not sure whether pumpkin was one of the dishes in the first thanksgiving dinner. But they were, however, a part of all traditional meals long before the arrival of the first Europeans. Most parts of the pumpkin are suitable for eating, including the shell, the seeds, the leaves, and even the flowers. When ripe, the pumpkin can be boiled, baked, steamed, or roasted.
E)
The pumpkin has been very important for centuries. It has been popular with wizards, witches and fairies. Maybe that’s why it is celebrated in so many festivals, folklore and fiction.
